Answer:
The complete question is;
What is not one of the ways that angiotensin II increases arterial blood pressure?
Angiotensin II triggers the sensation of thirst.
Angiotensin II stimulates the secretion of aldosterone.
Angiotensin II promotes vasodilation that decreases peripheral resistance.
Angiotensin II prompts the release of antidiuretic hormone (ADH).
Answer : Angiotensin II promotes vasodilation that decreases peripheral resistance.
Explanation:
Angiotensin is a group of peptide hormones (Angiotensin I-IV) that increases the blood pressure by vasoconstriction. A specialized structure in the kidney called Juxtaglomerular (JG) apparatus regulates blood pressure. It secretes an enzyme known as renin when the blood pressure drops below the normal level. Renin breaks up angiotensinogen, a protein synthesized by the liver into angiotensin I. Angiotensin I enters the bloodstream and is converted into Angiotensin II by Angiotensin-Converting Enzyme (ACE).
Angiotensin II binds to the receptors in the adrenal glands and stimulates aldosterone production. This hormone helps the kidneys to reabsorb salt (sodium). It also causes the constriction of arterioles (vasoconstriction), which results in increased blood pressure. Thus angiotensin II changes the way the blood is filtered and increases the water re-absorption by the kidneys, which results in the increase of blood volume. When the blood volume increases, it causes an increase in blood pressure. Angiotensin II also triggers the sensation of thirst and prompts the release of the pituitary gland’s anti-diuretic hormone (ADH).
